微电解/芬顿/蒸发/AO工艺处理丙硫菌唑农药废水
- Title:
- A Combined Process of Microelectrolysis, Fenton, Evaporation, and AO for Treating Prothioconazole Pesticide Wastewater
- 摘要:
- 采用微电解/芬顿/混凝沉淀/三效蒸发/EGSB/AO组合工艺处理丙硫菌唑农药废水，处理规模为150 m3/d。该组合工艺对去除生物毒性、盐分，提高B/C比，降低有机物浓度效果明显。运行结果表明，该工艺运行稳定，抗冲击负荷能力强。当平均进水COD、TDS、TN和TP浓度分别为43 378、45 376、1 830和23.3 mg/L时，出水浓度分别降至367、2 523、37.0和0.6 mg/L，各项出水指标均达到《污水综合排放标准》（GB 8978—1996）的三级标准，并满足工业园区污水处理厂的进水水质要求。
- Abstract:
- A combined process of microelectrolysis, Fenton, coagulation and sedimentation, tripleeffect evaporation, EGSB, and AO, was used to treat the prothioconazole pesticide wastewater with the treating capacity of 150 m3/d. It had obvious effects on removing biological toxicity and salinity, increasing B/C ratio and reducing organic concentration.The running results showed that the process operated stably and had strong resilience to shock loads. When the average influent concentrations of COD, TDS, TN and TP were 43 378, 45 376, 1 830 and 23.3 mg/L, the effluent concentration decreased to 367, 2 523, 37.0 and 0.6 mg/L respectively. All the effluent indicators could reach the third level criteria specified in Integrated Wastewater Discharge Standard(GB 8978-1996) and met the influent quality requirements of the sewage treatment plants in the industrial park.
